Add some weight to an arrow?

[JasonG]

Hey guys/girls, Im currently working on getting my bow set up for next year. I have some new arrows to go with it. Im shooting Goldtip hunter pro 340s with a 125 field tip, the arrow is weighing in at 418 grains. I would like to get my arrow weight closer to 500 grains. What is the best option? Im not to familiar with FOC . Could I just get heavier field points and then transition to heavy broad heads come this fall? Or would that make the arrow fly all weird. Sorry still learning this Archery thing! Thanks Jason

Must be short arrows/draw length?  Could opt for a heavier insert..

My arrows are 27"

If your running the gold tips get the fact system weights and you can put weight up front which makes a higher foc too.

I’m pretty sure you’ll need a stiffer spline if you add that much weight to the front. I would consider a heavier arrow to start with. But, you could try adding weight to the front and the nock end.

I bumped a thread up that has an foc calculator in it.
It's top of the bow hunting section right below this thread.

Thanks for the bump on the calculation thread. I'm hoping to use the arrows I have . I might not be able to get to 500 grains but would like to add some more weight if possible. It seems like most guys are using 100 -125 grain broardheads?

Came across this today. Something to think about “debunking the FOC theory”. Not saying any one way is better than the other. Just interesting.

You could use tube weights, it's a shaft that you would put inside your arrow. It won't change foc just overall weight.

You didn't say what your draw length,draw weight or what bow you shoot.
If 340 spine at 27" is where your bow tunes then going with 300's would allow you to leave them longer  gaining more gpi. Trying to make a short arrow heavy is kind of taking the long way around.

My bow is a hoyt definant turbo , my draw is 26” my draw weight is 65 lbs.

My personal thoughts are that your arrow weight is fine.  I try to stay in that window of 6 grains per pound of pull which would put you at 390 to 400.  I've killed plenty of elk with a 420 grain arrow.

Since you have gold tip now, I went to the gold tip site and used their spine chart.
Full length Kinetic Pierce Platinum in 250 spine 32"or full length Kinetic in 300 spine 30" will work and I came up with 485 and 486 grains. With heavier insert and maybe lumenoks your there.

Really don't need a 500 grn arrow in America. I was surprised how well a 370 grn arrow penetrated in africa.
